Functional Swallow-Related Outcomes Following Transoral Robotic Surgery for Base of Tongue Carcinoma

In an era where the incidence of oropharyngeal cancer is growing steadily, there have been few studies exploring functional outcomes for individuals whose definitive cancer management approach includes transoral robotic surgical (TORS) resection. This study was designed to examine swallow-related outcomes in individuals newly diagnosed with base of tongue cancer whose treatment plan included surgical resection via TORS. The aims of this study were to determine whether TORS resection for early stage BOT SCCA affected: (a) lingual strength, (b) swallow safety and efficiency, (c) oral intake, and (d) swallowing-related quality of life. Nine individuals meeting the inclusion criteria were recruited to participate from March 2017 to April 2018. Each participant was evaluated at four distinct time points: (a) preoperatively, (b) 1 week postoperatively, (c) 1 month postoperatively, and (d) 3 months postoperatively. The following data were collected at each time point: (a) maximum isometric lingual pressure, (b) Penetration-Aspiration Scale score, (c) Yale Pharyngeal Residue Severity Rating Scale scores, (d) Functional Oral Intake Scale score, and (e) EAT-10 score. Data analysis revealed that a significant decline in maximum isometric lingual pressure, EAT-10 scores, and Functional Oral Intake Scale scores occurred between preoperative baseline measurements and 1 week post surgery. All participants in the study demonstrated a return to levels at or near their baseline level of function for maximum isometric lingual pressure, EAT-10 score, and Functional Oral Intake Scale score by 1 or 3 months post surgery. There were no significant changes in swallow safety or efficiency observed at any time point during the study.

Volume and Location of the Defect as Predictors of Swallowing Outcome After Glossectomy: Correlation with a Classification.

This study aimed to characterize the swallowing outcomes after glossectomy and analyze factors affecting them. An attempt is made to propose a classification system and corroborate it to the results. This is a cross-sectional study to assess swallowing in carcinoma tongue patients treated surgically with or without reconstruction, followed by adjuvant therapy as indicated. One hundred and six patients were evaluated with videofluoroscopy (VFS). Volume defects were classified as I: less than one-third, II: one-third to half, III: half to two-thirds, IV: two-thirds to total glossectomy. Location was assigned as lateral, tip, and sulcus defects. Predictors were T stage, surgical approach, volume, location, and adjuvant radiotherapy. Chi-square and logistic regression were used for statistical analysis. Defects were Class I, II, III, and IV in 36, 42, 16, and 12 patients, respectively. Adjuvant radiotherapy was given in 40% of cases. Mean evaluation time was 14months from treatment. On, Functional Oral Intake Scale (FOIS) score, as the Class of the defect increased, the percentage of patients with low scores (poor swallowing outcomes) showed an increasing trend (p < 0.001). Defect volume, T stage, approach, and radiotherapy correlated significantly with an abnormality of all VFS parameters (p < 0.001). On multivariate analysis, defect volume remained an independent predictor for oral parameters; radiotherapy emerged as the only independent predictor for pharyngeal parameters. The incremental volume of the defect is a significant independent predictor of swallowing. Based on this, we propose a classification for glossectomy.

Efficacy of speech therapy in post-intubation patients with oropharyngeal dysphagia: a randomized controlled trial.

to verify the efficacy of speech therapy in the early return of oral intake in patients with post-orotracheal intubation dysphagia. It was a double-blinded randomized controlled trial for two years with patients of intensive care units of a hospital. Study inclusion criteria were orotracheal intubation>48hours, age≥18 years old, clinical stability, and dysphagia. Exclusion criteria were tracheotomy, score 4 to 7 in the Functional Oral Intake Scale (FOIS), neurological disorders. Patients were randomized into speech treatment or control group (ten days of follow-up). The treated group (TG) received guidance, therapeutic techniques, airway protection and maneuvers, orofacial myofunctional and vocal exercises, diet introduction; the control group (CG) received SHAM treatment. Primary outcomes were oral intake progression, dysphagia severity, and tube feeding permanence. In the initial period of study, 240 patients were assessed and 40 (16.6%) had dysphagia. Of this, 32 patients met the inclusion criteria, and 17 (53%) received speech therapy. Tube feeding permanence was shorter in TG (median of 3 days) compared to CG (median of 10 days) (p=0.004). The size effect of the intervention on tube feeding permanence was statistically significant between groups (Cohen's d=1.21). TG showed progress on FOIS scores compared to CG (p=0.005). TG also had a progression in severity levels of Dysphagia protocol (from moderate to mild dysphagia) (p<0.001). Speech therapy favors an early progression of oral intake in post-intubation patients with dysphagia. Clinical Trial Registration: RBR-9829jk.

Clinical Swallowing Profile Change in HNC Patients Treated with C/RT.

To demonstrate utility of the Mann Assessment of Swallowing Ability-Cancer (MASA-C) to describe change in swallowing ability in a cohort of HNC patients from pre-C/RT to post-C/RT to follow up at 3 months post-C/RT. An exploratory analysis compared patients treated with radiotherapy (RT) only to patients treated with chemoradiation (CRT). Prospective Cohort. The MASA-C and Functional Oral Intake Scale (FOIS) were completed on 85 HNC patients within the first 5 days of CRT initiation, at the completion of C/RT (6 weeks), and 3 months after completion of C/RT. MASA-C total scores and clinical profiles were used to describe change in swallowing performance at each time point. MASA-C and FOIS scores were significantly lower at 6 weeks and 3 months compared to baseline. Patients treated with CRT demonstrated more frequent and more severe dysphagia. Post C/RT items demonstrating the most deterioration included taste, diet level, oral mucosa, saliva, weight loss, and pharyngeal functions. Significant recovery was observed between 6 weeks and 3 months on both the MASA-C and FOIS. MASA-C items revealing the greatest recovery included taste, diet level, oral mucosa, tongue movement, weight loss, oral transit, voice, and pharyngeal phase. Few significant differences were noted between RT and CRT cases at 3 months. Swallowing functions deteriorate significantly following C/RT with incomplete recovery at 3 months. Few differences were noted between RT and CRT treated patients at 3 months. Clinical profiling with the MASA-C provides a standard, simple method to document swallow function change over time in these patients. 2 Laryngoscope, 131:E1873-E1880, 2021.

Quality of life in tongue cancer treated patients before and after speech therapy: a randomized clinical trial

IntroductionTongue cancer is one of the most common subtypes of head and neck cancer. The aggressive effects of treatment cause aesthetic, psychosocial and functional deficits, especially dysphagia, which affects patient quality of life. Rehabilitation, which is essential for functional maximum recovery, helps patients deal with new and altered structures and has a positive impact on quality of life. ObjectiveTo verify the impact of speech therapy on swallowing quality of life in tongue cancer patients after treatment. MethodsThis parallel randomized clinical trial was conducted at a public hospital in Porto Alegre, RS, Brazil. Before and after the intervention, a quality of life questionnaire (the Deglutition Handicap Index) was employed, dysphagia severity was assessed with fiberoptic endoscopic evaluation of swallowing, and the Functional Oral Intake Scale carried out. The experimental group underwent four-week sessions of speech therapy over one month, while the control group received the institution’s usual follow-up. ResultsThirty individuals treated for tongue cancer were divided into a study and a control group. Deglutition Handicap Index scores decreased significantly (approximately 40 points) (p < 0.001) after the intervention in the study group. There was a significant correlation between improved quality of life, reduced dysphagia severity and increased in Functional Oral Intake Scale scores (p < 0.001). ConclusionAfter speech therapy, quality of life scores related to deglutition and dysphagia severity improved in patients treated for tongue cancer.

Critical illness polyneuromyopathy: Functional impact after severe acquired brain injuries.

Critical illness polyneuropathy and myopathy (CIPNM) frequently affects critical patients and can occur after severe acquired brain injuries (sABI) influencing the functional recovery. We aimed to assess how the concomitance between CIPNM and sABI might influence the rehabilitative outcomes in terms of functional autonomy, oral feeding recovery and endotracheal tube weaning. Adult patients with sABI admitted to an intensive rehabilitation unit and underwent an electromyography examination within seven days after admission were included. Assessed rehabilitative outcomes at discharge were decannulation success and its timing, functional autonomy measured by the Functional Independence Measure (FIM) and the Glasgow outcome scale expanded (GOS-E) and oral feeding recovery assessed by the Functional Oral Intake Scale (FOIS) score. Among the 224 included patients (81 (36%) females, age (median[IQR]): 68.73[21.66] years), 119 (53.1%) presented CIPNM at admission. Albeit the change of rehabilitative outcomes between admission and discharge was significant in all the sABI patients (P<.001 for ΔFOIS, ΔFIM and ΔGOS-E), those with a concomitant CIPNM achieved significantly lower scores as evaluated by Mann-Whitney tests (P<.001 for ΔFIM Δ and GOS-E; P<.005 for ΔFOIS). The CIPNM absence was associated with a higher probability to achieve functional autonomy (GOS-E>4) (OR:4.57 (1.49/14.06); P<.01) and oral feeding recovery (FOIS≥4) (OR:2.07 (1.07/3.99); P=.03) at discharge. CIPNM presence did not influence decannulation success but a longer time to cannula weaning was required (P<.01 in the log-rank test). CIPMN significantly affects the rehabilitative outcomes after a sABI and should be taken into account for better rehabilitative handling.

Functional and survival outcomes in elderly patients undergoing transoral robotic surgery.

To determine if elderly patients (≥70years) have differences in functional and survival outcomes compared to non-elderly patients (<70years) following transoral robotic surgery. A retrospective cohort study was conducted on patients undergoing robotic surgery for head and neck cancer at a tertiary institution from 2011 to 2016. Functional status was evaluated with diet, enteric feeding status, Functional Oral Intake Scale (FOIS), tracheostomy tube placement, and unplanned readmission. Kaplan Meier method and Cox proportional hazard model were used to assess overall survival (OS) and disease-free survival (DFS) between elderly and non-elderly patients. Two hundred and forty-six patients met inclusion criteria. The mean age of the cohort was 63.5±9.74years. There were 64 patients (26.0%) that were ≥70years. Elderly patients were more likely to be discharged with enteric access (p<0.002). As early as 3months, there was no significant difference in need for enteric feeds, diet, or FOIS score. There was no difference in tracheostomy tube rates and unplanned readmission between both cohorts. There was no significant difference in OS and DFS between age groups when stratified by p16 status. Elderly patients are more likely to require perioperative enteric feeding, but 3-month, 1-year, and 2-year functional outcomes are comparable to younger patients. Survival outcomes are similar in both populations.

Relationship between the Functional Oral Intake Scale (FOIS) and the Self-Efficacy Scale among Cancer Patients: A Cross-Sectional Study.

A few studies have provided detailed reports suggesting that subjective swallowing disorders may be related to dysphagia. Therefore, we verified the relationship between oral health-related self-efficacy and dysphagia severity in cancer treatment using a cross-sectional study. Participants included patients undergoing treatment for cancer at Shimane University Hospital in Shimane, Japan, and those receiving outpatient treatment at the hospital’s Oral Care Center between August 2018 and April 2019. In all, 203 participants enrolled in the study and completed the Functional Oral Intake Scale (FOIS), the Self-efficacy Scale for Advanced Cancer (SEAC), and the Oral Health-related Self-Efficacy Scale for Patients with Cancer (OSEC). Multivariate analysis showed a statistically significant correlation between the low FOIS score and the SEAC subscales of Activities of Daily Living Self-efficacy (ADE) (odds ratio 1.04, 95% [CI] 1.00–1.07) and Symptom Coping Self-efficacy (SCE) (odds ratio 0.61, 95% [CI] 0.42–0.88). Based on the Jonckheere-Terpstra test, the SEAC and the OSEC tended to increase as the category of the FOIS progressed. To conclude, self-efficacy played an important role in dysphagia and may affect the severity of dysphagia in cancer patients.

The natural history of weight and swallowing outcomes in oropharyngeal cancer patients following radiation or concurrent chemoradiation therapy.

Patients treated for oropharyngeal cancer (OPC) are at increased risk for functional decline due to cancer-related impairments and treatment toxicities, often leading to recommendations for enteral nutritional support. This study investigated the natural history of weight and swallowing outcomes in patients with and without feeding tube (FT) placement. Data were collected from electronic medical records of OPC patients treated with (chemo)radiotherapy at a single regional cancer center between January 2013 and December 2015. Weight measurements, Functional Oral Intake Scale (FOIS) scores, Performance Status Scale for Head and Neck Cancer (PSS-HN) normalcy of diet scores, and M.D. Anderson Dysphagia Inventory (MDADI) composite scores were gathered at baseline and at 3-, 6-, and 12-months post-treatment. Patients were grouped based on FT placement and change over time was assessed using linear mixed effects analysis. Of 122 eligible patients, 38 (31.1%) received a FT (FT group). Compared with baseline, weight decreased significantly at 3 and 6months in both groups and at 12months for patients without a FT (NFT group). Swallowing-related quality of life (QoL) decreased significantly at 3 and 6months only in the NFT group. OPC patients experience clinically relevant decreases in weight and swallowing-related QoL in the first-year post-treatment irrespective of FT placement. These findings will contribute to improved patient monitoring and communication within the clinical setting which may ultimately lead to better outcomes for those with OPC.

Effect of dysphagia rehabilitation in patients receiving enteral nutrition at home nursing care: A retrospective cohort study.

ObjectiveWe considered the effect of dysphagia rehabilitation and investigated parameters associated with the resumption of oral intake in the elderly patients receiving home nursing care who were not eating by mouth.MethodsThe participants were 116 patients aged ≥65 years (66 men and 50 women, mean age 79.7 ± 8.9 years) who were receiving home nursing care and not eating by mouth because of dysphagia. All patients underwent dysphagia rehabilitation for 6 months with the objective of resuming oral intake. After 6 months of dysphagia rehabilitation, the patients’ eating status was assessed using the Functional Oral Intake Scale (FOIS) and the associations of the post‐intervention FOIS score with age, history of pneumonia, duration of enteral nutrition, body mass index (BMI), alertness, physical function (ability to walk) and swallowing function at the initial examination.ResultsFunctional Oral Intake Scale scores increased significantly after 6 months rather than those at the initial evaluation (P < .001). Eighty patients (69.0%) resumed oral intake (FOIS score ≥2), thirty patients (25.9%) of whom became capable of daily oral intake (FOIS score ≥3). Swallowing function was associated with the resumption of oral intake. In addition, physical function before dysphagia rehabilitation was an important factor to resume daily oral intake.ConclusionsThe results of the present study suggest that the resumption of oral intake by patients receiving enteral nutrition requires improvement in swallowing function. In addition, anyone who cannot walk may not recover daily oral intake.

Simultaneous evaluation of symptoms, swallowing functions, and patient-reported swallowing difficulties and their correlations with ingestion status during definitive chemoradiotherapy for oropharyngeal and hypopharyngeal cancer.

To clarify the correlations among symptoms, swallowing functions, and ingestion status and to validate a method of swallowing evaluation during chemoradiotherapy (CRT) for head and neck cancer. Oropharyngeal and hypopharyngeal cancer patients who were to receive definitive CRT as initial treatment were included in this prospective, single-center, observational study. The Functional Oral Intake Scale (FOIS) for ingestion status and grades of symptoms (dryness, dysgeusia, mucositis, and the analgesic ladder); the Yale Pharyngeal Residue Severity Rating Scale on fiberoptic endoscopic evaluation of swallowing (FEES) and the Penetration-Aspiration Scale (PAS) on videofluoroscopic (VF) evaluation for swallowing functions; and the 10-item Eating Assessment Tool (EAT-10) questionnaire were assessed at 5 time points unless the participant refused. The FEES and VF evaluation findings at each point were also compared. There were 38 participants. Dysgeusia, mucositis, and pain grade, as well as the FOIS score, were the worst at 70Gy and then improved after treatment. The improvements of pharyngeal residue and the PAS after treatment were limited. The EAT-10 and the pain ladder were highly correlated with the FOIS changes at many time points. The VF evaluation rate dropped after 40Gy, whereas the FEES rate remained high. There were good correlations between pharyngeal residue and the PAS at 0Gy, 70Gy, and 3months. The EAT-10 and pain reflected the FOIS score changes well, while two swallowing evaluations did not. To avoid aspiration, VF evaluation may not be necessary during CRT because of high correlations with pharyngeal residue on FEES.

Swallowing Outcomes and Discharge Destinations in Acute Stroke Tube-Feeding Dependent Dysphagia Patients Treated With Neuromuscular Electrical Stimulation During Inpatient Rehabilitation.

Inpatient rehabilitation study comparing swallowing outcomes and discharge destinations in acute stroke tube-feeding dependent dysphagia patients treated with neuromuscular electrical stimulation and traditional dysphagia therapy versus those treated with only traditional dysphagia therapy. Retrospective case-control study including 359 patients with acute stroke having initial Functional Oral Intake Scale scores of 3 or lower (profound to severe tube-feeding dependent dysphagia). One hundred ninety participants received neuromuscular electrical stimulation with traditional dysphagia therapy, and 169 controls received only traditional dysphagia therapy. Treatment occurred in hourly sessions 5 d/wk. Main outcome measures were comparison of Functional Oral Intake Scale scores after treatment (N = 359) and comparison of discharge destinations (n = 267). The neuromuscular electrical stimulation posttreatment mean ± SD Functional Oral Intake Scale score was 4.21 ± 2.1 versus 2.94 ± 1.96 for controls (t = 5.85, P < 0.001). The neuromuscular electrical stimulation group posttreatment mean ± SD Functional Oral Intake Scale gain was 3.24 ± 2.26 points versus 1.87 ± 2.01 for controls (t = 6.05, P < 0.001). After treatment, 51.6% (98/190) neuromuscular electrical stimulation patients had minimal or no swallowing restrictions (Functional Oral Intake Scale scores = 5-7), whereas only 26.6% (45/169) controls improved with Functional Oral Intake Scale scores of 5-7 (χ = 23.3, P < 0.0001). Groups differed by discharge destinations: neuromuscular electrical stimulation having more discharges to community than controls, 60% versus 44% (χ = 9.16, P = 0.003), and neuromuscular electrical stimulation having fewer acute care transfers compared with controls, 8% versus 25% (χ = 32.7, P < 0.0001). Neuromuscular electrical stimulation with traditional dysphagia therapy was associated with better discharge swallowing outcomes and Functional Oral Intake Scale scores than traditional dysphagia therapy alone during inpatient rehabilitation in treating acute stroke feeding tube-dependent dysphagia and was associated with more discharges to community and less transfers back to acute care.

Respiratory muscle training in stroke patients with respiratory muscle weakness, dysphagia, and dysarthria - a prospective randomized trial.

Objective:To examine the efficacy of combined inspiratory and expiratory respiratory muscle training (RMT) with respect to the swallowing function, pulmonary function, functional performance, and dysarthria in patients with stroke.Design:Prospective, randomized controlled trial.Setting:Tertiary hospital.Participants:The trial included 21 subjects (12 men, 9 women) aged 35 to 80 years presenting with 6 months history of unilateral stroke, respiratory muscle weakness (≥70% predicted maximal inspiratory pressure (MIP) and/or ≤70% maximal expiratory pressure (MEP)), dysphagia, or dysarthria. These subjects were randomly assigned to the control (n = 10, rehabilitation) and experimental (n = 11, rehabilitation with RMT) groups.Intervention:Inspiratory RMT starting from 30% to 60% of MIP and expiratory RMT starting from 15% to 75% of MEP for 5 days/week for 6 weeks.Main outcome measures:MIP, MEP, pulmonary function, peak cough flow, perception of dyspnea, Fatigue Assessment Scale, Modified Rankin Scale, Brunnstrom stage, Barthel index, Functional Oral Intake Scale (FOIS), and parameters of voice analysis.Results:Significant differences were observed between both groups in terms of MIP, forced vital capacity (FVC), and forced expiratory volume per second (FEV1) of the percentage predicted. Significant difference was found with respect to the change in fatigue, shimmer percent, amplitude perturbation quotient, and voice turbulence index (VTI) according to the acoustic analysis in the RMT group. The FEV1/FVC ratio was negatively correlated with jitter percent, relative average perturbation, pitch perturbation quotient, and VTI; the maximum mid-expiratory flow (MMEF) and MMEF% were also negatively correlated with VTI. Significant differences among participants of the same group were observed while comparing the Brunnstrom stage before and after training of the affected limbs and the Barthel scale and FOIS scores in both the groups.Conclusions:Altogether, 6-week combined inspiratory and expiratory RMT is feasible as adjuvant therapy for stroke patients to improve fatigue level, respiratory muscle strength, lung volume, respiratory flow, and dysarthria.Clinical trial registration number (Clinical Trial Identifier): NCT03491111.

Predicting Swallowing Outcomes from Objective Videofluoroscopic Timing and Displacement Measures in Head and Neck Cancer Patients.

Radiation therapy with or without chemotherapy compromises swallowing efficiency and safety in patients with head and neck cancer (HNC). The resulting dysphagia leads to overall morbidity, with altered diets, reduced nutritional intake, reduced quality of life, and potential interruption of curative cancer treatment. Despite well-documented radiation-related changes in swallowing physiology, scarce research exists on the potential clinical value for measurements of swallowing timing and displacement in this population. This study investigated the discriminatory value of quantitative timing and displacement parameters for the Functional Oral Intake Scale and Penetration Aspiration Scale scores using pre- and post-radiation videofluoroscopy data. Swallowtail Software Version 1 (Belldev Medical, Arlington Heights, IL) was used to obtain objective timing and displacement measurements from the pre- and post-radiation videofluoroscopy data for 31 patients who underwent radiation therapy, with or without chemotherapy, for head and neck cancer. The total pharyngeal transit time (BP2) (p < 0.000, r = 0.43) in pudding bolus trials and the maximal upper esophageal sphincter opening (PESMax/cm) (p = 0.001, r = 0.31) in thin bolus trials were discriminatory for Functional Oral Intake Scale (FOIS). Findings suggest that measurement of post-radiation changes using objective and quantitative parameters may offer some discriminatory value regarding future dysphagia risk and prognosis based on total pharyngeal transit time and degree of UES opening. In addition, the results suggest that different bolus types may offer different discriminatory values in HNC population, and that some timing and displacement variables may have discriminatory value for patients' diet levels independent from any aspiration risk.

Abstract TMP46: Fostering Eating After Stroke (FEAST) Trial: A Randomized Controlled Trial of Non-Invasive Brain Stimulation for Improving Dysphagia After Stroke

Background: Effective therapy for dysphagia recovery after stroke is currently lacking. We conducted a phase-2 RCT to investigate the effects of anodal transcranial direct current stimulation (atDCS) in reducing aspiration risk, improving diet, and analyzed its safety in the acute-subacute stroke phase. Hypothesis: Since swallowing has bi-hemispheric representation targeted atDCS to the unaffected hemisphere combined with swallowing exercises may improve dysphagia from a unilateral hemispheric infarction [UHI]. Methods: This phase-2, double-blind, RCT enrolled subjects with dysphagia [penetration and aspiration (PAS) score ≥ 4], from an acute-subacute UHI [day 2-day 6 after stroke onset] and randomized them into 3 groups: low-dose atDCS [2 mA atDCS alternating with sham twice daily], high-dose atDCS [2 mA atDCS twice daily] or sham [twice daily]. All sessions were performed with standardized swallowing exercises for 20 minutes over 5 days. Major safety outcomes were incidence of seizures, worsening of neurological and swallowing functions and mortality; primary efficacy outcome was a change in PAS scores between day 1 and 5 of intervention; main dietary outcome was a change in dietary intake at 1 month using the Functional Oral Intake scale (FOIS). Results: Of the planned 99 subjects, 42 could be enrolled in the funding period. No group differences in pre-defined safety outcomes were observed. Mean (SD) change in PAS score from baseline to final session was -0.8 (±1.6) in sham, -0.8 (±1.5) in low-dose and -0.4 (±1.2) in high dose groups. Adjusting for baseline PAS, NIHSS scores and age, means (SE) were -0.96 (0.33) in sham, -0.81 (0.36) in low-dose and -0.34 (0.35) in high dose; there were no significant pairwise differences (p&gt;0.40). Mean (SD) changes in FOIS scores from baseline to 1 month were: 2.1 (±1.7) in sham, 2.5 (±1.7) in low-dose and 2.9 (±1.2) in high dose. Adjusted means (SE) were 2.07 (0.35) in sham, 2.46 (0.38) in low dose and 3.05 (0.38) in high dose (pairwise p &gt; 0.15). Conclusion: Application of atDCS to the unaffected hemisphere is safe in the acute-subacute stroke phase but did not decrease aspiration risk in this phase-2 RCT. Higher doses of atDCS were associated with better dietary scores but group differences were not statistically significant.

Abstract TP157: Functional Oral Intake Scale is Associated With Poorer Outcomes Following Stroke

Background: Stroke is the leading cause of disability in adult life. Oropharyngeal dysphagia occurs in 65-90% of patients, and its identification in the acute phase of stroke can prevent complications. Objective: Verify whether Functional Oral Intake Scale (FOIS) score during stroke hospitalization is associated with functional capacity, as assessed by the modified Rankin Scale (mRs), and mortality 90 days after stroke. Methods: A prospective cohort study evaluating 201 patients hospitalized in the Stroke Unit was carried out. Dysphagia was evaluated during hospitalization using both a specific protocol to evaluate swallowing biomechanics and FOIS, in which FOIS 1-3 - tube feeding, 4-5 - oral feeding requiring food consistency changes, and 6-7 - oral feeding with no changes in food consistency. mRs≥3 90 days after discharge was considered disability. The data were adjusted for the NIHSS score, sex, age, type of stroke, and presence of thrombolysis. Significance level of 5%. Results: Of the 201 patients evaluated, 42.8% (86) who had dysphagia were older, had a higher severity of stroke, and pneumonia rate . A FOIS score of 6-7 may be a protective factor against disability (mRs≥3) (OR:0.17; CI:0.005-0.56; p=0.004), and FOIS 1-3 at hospital discharge increased the risk of mRs≥3 (OR:14.97; CI: 2.68-83.65; p=0.002) and mortality (OR:9.79; CI:2.21-43.4; p=0.003) within 90 days after stroke. Pneumonia was the leading cause of death, however dysphagia and FOIS 1-3 at discharge were associated with death from any cause. Important to highlight that the interaction of FOIS 1-3 at discharge and pneumonia further enhanced mortality chance (OR:113; CI:1.40-9.097; p=0.035). Conclusion: Dysphagia or FOIS 1-3 at discharge are markers of poor prognosis after stroke. Our data suggest the importance of early evaluation of dysphagia and closely monitoring the tube fed patients following stroke.

Aspiration pneumonia in elderly stroke patients in a convalescent rehabilitation ward: Risk factors and effects on recovery after stroke

To clarify risk factors for aspiration pneumonia and the effects of aspiration pneumonia on the recovery after stroke in elderly stroke patients in a convalescent rehabilitation ward. We conducted a retrospective study of 463 stroke patients with dysphagia who were ≥65 years of age (mean age, 80.2±8.1 years) who were admitted to our convalescent rehabilitation ward. Information was obtained from medical charts. A multivariate analysis was performed to clarify risk factors for aspiration pneumonia and the association between aspiration pneumonia and increased functional oral intake scale and functional independence measure motor scores. For the increase in functional independence measure motor score, values of ≥16 points and ≤15 points were coded as 1 and 0, respectively. Aspiration pneumonia developed in 52 patients. The multivariate analysis revealed that male sex (odds ratio [OR] 3.07, 95% confidence interval [CI] 1.59-5.95, p<0.001), geriatric nutritional risk index (OR for one unit increase 0.94, 95% CI 0.90-0.97, p<0.001) and tube feeding (OR 3.89, 95% CI 1.71-8.83, p=0.001) on admission were significant predictors of aspiration pneumonia. Aspiration pneumonia was associated with increased functional oral intake scale scores (OR 0.29, 95% CI 0.12-0.66, P=0.003) and increased functional independence measure motor scores (OR 0.23, 95% CI 0.09-0.55, P=0.001). Male sex, undernutrition and tube feeding on admission are risk factors for aspiration pneumonia. Aspiration pneumonia is suggested to be associated with recovery of the oral intake of food and activities of daily living.

What Factors Affect Changes in Body Composition and Swallowing Function in Patients Hospitalized for Oral Cancer Surgery?

PurposeThere are few studies about sarcopenia before and after surgery for oral cancer. Therefore, we examined body composition during hospitalization and factors affecting weight loss, skeletal muscle mass index (SMI) reduction, and swallowing function at discharge in this patient group.Patients and MethodsA prospective survey was conducted at Tokyo Medical and Dental University Dental Hospital for patients who underwent primary surgery for oral cancer and reconstruction using free flaps. We compared body weight, SMI, grip strength, and walking speed at admission and discharge. We also examined factors affecting weight loss and SMI reduction and the functional oral intake scale (FOIS) score at discharge.ResultsThere were 26 patients that we could survey during the period. As a result of Wilcoxon’s signed-rank test, body weight, SMI, and grip strength were significantly reduced during hospitalization, but no reduction was noted for sarcopenia. As a result of multiple regression analysis, postoperative chemoradiotherapy was a risk factor for weight loss, reduced SMI, and low FOIS score at discharge.ConclusionPostoperative chemoradiotherapy is a risk factor for weight loss, muscle mass loss, and dysphagia at discharge, and chemoradiotherapy may affect rather than an invasion of surgery. After surgery, besides follow-ups for cancer, oral cancer patients should be followed up to assess dysphagia, undernutrition, and sarcopenia.

The effectivity of pharyngeal strengthening exercise, hyolaryngeal complex range of motion exercise, and swallowing practice in swallowing function of ischemic stroke patients with neurogenic dysphagia.

Dysphagia is associated with an increased risk of aspiration pneumonia which often results in death in stroke patients. Therefore, effective and efficient management is important. Behavioral therapy for swallowing rehabilitation based on the principles of neuroplasticity such as oropharyngeal strengthening and range of motion exercises are the alternative ones that often be used. This study aimed to assess the changes in swallowing function in ischemic stroke patients with neurogenic dysphagia after pharyngeal strengthening exercise, hyolaryngeal complex range of motion exercise and swallowing practice. Swallowing function was assessed using Penetration Aspiration Scale (PAS) and Functional Oral Intake Scale (FOIS) based on Flexible Endoscopic Evaluation of Swallowing before and after interventions. The interventions were given every day with a duration of 30–45 minutes for 4 weeks. There were six subjects who completed the study. The PAS before the interventions were 6.00±1.79 and after the interventions was 1.67±0.82 (P=0.003). Meanwhile, the FOIS score before the interventions was 3 (1–5) and after the interventions were 5.00±2.10 (P=0.041). There was an improvement of PAS and FOIS after the interventions. Therefore, the interventions can be suggested to be used as one of the treatments to improve swallowing function in ischemic stroke patients with neurogenic dysphagia.

The effect of intensified nonverbal facilitation of swallowing on dysphagia after severe acquired brain injury: A randomised controlled pilot study.

BACKGROUND:There is little high-level evidence for the effect of the nonverbal facilitation of swallowing on swallowing ability in the subacute stage of rehabilitation following severe acquired brain injury (ABI).OBJECTIVE:To pilot test a randomised controlled trial to determine the effect of an intensification of the nonverbal facilitation of swallowing on dysphagia.METHODS:Ten patients with severe ABI and dysphagia were randomised into two groups at a highly specialised neurorehabilitation clinic.The intervention group received an intensification of the nonverbal facilitation of swallowing and the control group received basic care of the face and mouth in addition to treatment as usual for two sessions of 20 minutes per day for three weeks.Outcomes were Functional Oral Intake Scale (FOIS), Penetration Aspiration Scale (PAS), and electrophysiological swallowing specific parameters (EMBI).RESULTS:The intensified intervention was feasible. PAS and FOIS scores improved in both groups, with no differences between groups. The swallowing specific parameters reflected clinically observed changes in swallowing.CONCLUSIONS:PAS and FOIS are feasible instruments to measure dysphagia. It is possible and valid to measure swallowing frequency and kinematics using electromyography and bioimpedance. The definitive study should have widened inclusion criteria and optimise intervention timing to maintain patient arousal.
